I think we also have reports of mhttpd crash on macos with safari from the Dragon experiment,
but cannot reproduce the problem.

If you can reproduce this, can you capture the crash stack trace?

One way to do this is to enable core dumps in odb "/expt/enable core dumps" set to "y", restart mhttpd,
wait for the crash. I think macos writes core dumps into /cores/... Or you can run mhttpd inside lldb
and wait for the crash. the lldb command to show the stack trace is "bt", but you may need
to switch to different threads to see which one actually crashed. I forget what the command
for that is.

BTW, the mhttpd networking code has not changed in a long time, but an update
of mongoose web server library is overdue (to fix a memory leak, at least).
